Hard Tooth Surface Reductor Introduction
Hard tooth surface reductor is widely used in metallurgy, mining, lifting, transport, cement, construction,
chemical, textile, printing and dyeing, pharmaceutical, and other fields. Machine of decelerate of hard tooth flank,
it is a kind of dynamic convey institutions, the use of gear speed converter,
the motor of rotary rotary deceleration to want, and get a bigger torque device.
Hard tooth surface reductor is a relatively sophisticated machinery,
the use of its purpose is to reduce speed and increase torque,
suitable for high speed spindle speed is not more than 1500 r/min,
gear circumferential velocity is not more than 20 m/s, working environment temperature is 45 ℃ and 40 ℃ - environment.
Hard Tooth Surface Reductor Characteristics
(1)The center distance, nominal transmission ratio etc.
The main parameters optimization design, main parts and components interchangeability.
(2)Gears adopt high quality alloy steel by carburizing, quenching, and become, tooth surface hardness HRC54-62.
(3)Small volume, light weight, high precision, large capacity,
high efficiency, long life, high reliability, smooth transmission, low noise.
(4)General use oil , natural cooling, when thermal power can't meet,
can adopt circulating oil lubrication or fan, cooling coil cooling.
Hard Tooth Surface Reductor Selection Methods
1、The known parameters and conditions
The name of the prime mover,Power P1= kW rotate speedn1= r/min
The name of the machine work,PowerP2= kW rotate speed n2= r/min
The requirements of the transmission ratioi=n、/n, Working hours every day h,
Start times per hour,Cycle per hour %.
Load characteristics, impact, serious impact on the smooth () reliability requirements (generally, high, high)
Environment temperature ℃,The cooling conditions,cooling water temperature ℃
On the drive gear shaft coupling model. Whether to bear other additional force.
Any other special requirements
2、According to the rated power specifications
The nominal input power of the series parallel shaft gear box P.
(sheet9—20)According to the load smoothly, every day work time less than or equal to 10 h,
start no more than five times per hour. Allow startup torque for the job twice as much torque. One-way operation, single gear contact strength safety coefficient of about 1,
failure rate is less than or equal to 1%, calculate and determine the conditions of, and gear box two-way operation. Need to see a circumstance to PA multiplied by the coefficient of 0.8 1.0,
when the reverse load, frequent commutation, selection of reliability coefficient K.
Low coefficient of small value. Instead take larger value,
and the power rating for the selected gear box must be satisfie.P(P:KAK;K ≤PA
Pc—Computing power
P2—The working machine power
KA—Coefficient of performance.
KS—Start the coefficient
KR—reliability coefficient
3、According to the allowable thermal power check
Series parallel shaft gear box of permissible thermal power P,
suitable for ambient temperature 20 c. continuous operation and power utilization rate of 100% per hour (P2 / P1, 100%)
to 100% of the time, conditions are not required to be revised at the same time.
